Figure 4.
After comparison among the four groups, five low-molecular metabolites were selected, namely decanoylcarnitine, γ-glutamylphenylalanine, lysophosphatidyl glycerol (18 : 1), CMP-N-glycoloylneuraminate, and meloside (L.) The intensity values of these five metabolites in each group can be intuitively reflected by box plots.
